Re: [eclipselink-users] ReadAll queries ignores cache

HI Mohamed,

ReadAll queries must go to the database to get the primary keys - to ensure that all the elements in the database are returned since there is no guarantee all the elements can be found in the cache.

  For objects that exist in the cache, the query will return those objects.

Hi all,

I have a find all query like this:

@NamedQuery(name = "Department.findAll", query = "SELECT d FROM Department
hints = {
   @QueryHint(name = "eclipselink.cache-usage", value =
   @QueryHint(name = "eclipselink.query-type", value = "ReadAll")

The query still goes to the database everytime. Does Eclipselink ignores
cache for read all?

Thanks in advance,
